QuickBlox VideoChat演示未调用OnOpponentVideoDataReceived

Question

我在QuickBlox中使用OnQBVideoChatListener时出现问题，从不调用onOpponentVideoDataReceive和onOpponentAudioDataReceive两种方法。以下是我实现cameraView和opponentView的方法。它与给定here的示例应用程序基本相同。我试图在我的手机和平板电脑上运行示例视频聊天应用程序然而同样的问题发生，只有cameraView得到更新。对手的观点总是黑的。有没有人经历过同样的麻烦并有解决方案？

非常感谢！

private void initViews() {

    // Setup UI
    opponentView = (OpponentGlSurfaceView) findViewById(R.id.opponentView);
    cameraView = (CameraView) findViewById(R.id.cameraView);

    cameraView.setCameraFrameProcess(true);
    // Set VideoChat listener
    cameraView.setQBVideoChatListener(qbVideoChatListener);

    // Set Camera init callback
    cameraView.setFPS(6);

    cameraView.setOnCameraViewListener(new OnCameraViewListener() {
        @Override
        public void onCameraSupportedPreviewSizes(List<Camera.Size> supportedPreviewSizes) {
            Camera.Size firstFrameSize = supportedPreviewSizes.get(0);
            Camera.Size lastFrameSize = supportedPreviewSizes.get(supportedPreviewSizes.size() - 1);
            cameraView.setFrameSize(firstFrameSize.width > lastFrameSize.width ? lastFrameSize : firstFrameSize);
        }
    });

    // VideoChat settings
    videoChatConfig = (VideoChatConfig) GlobalVar.getObject(tag);

    try {
        QBVideoChatController.getInstance().setQBVideoChatListener((QBUser)GlobalVar.getObject(GlobalVar.CURRENT_USER_KEY), qbVideoChatListener);
    } catch (XMPPException e) {
        e.printStackTrace();
    }

}


OnQBVideoChatListener qbVideoChatListener = new OnQBVideoChatListener() {
    @Override
    public void onCameraDataReceive(byte[] videoData) {
        if (videoChatConfig.getCallType() != CallType.VIDEO_AUDIO) {
            //... 
        }
        else{
            QBVideoChatController.getInstance().sendVideo(videoData);
            Log.i(tag,"videoData sent!");  // THIS IS EXECUTED
        }
    }

    @Override
    public void onMicrophoneDataReceive(byte[] audioData) {
        QBVideoChatController.getInstance().sendAudio(audioData);
        Log.i(tag,"AudioData sent!");  //SO IS THIS 
    }

    @Override
    public void onOpponentVideoDataReceive(byte[] videoData) {
        Log.i(tag,"received img from opponent");   //NOT CALLED 
        opponentView.loadOpponentImage(videoData);
    }

    @Override
    public void onOpponentAudioDataReceive(byte[] audioData) {
        Log.i(tag,"received Audio from opponent");   //NOT CALLED
        QBVideoChatController.getInstance().playAudio(audioData);
    }

    @Override
    public void onProgress(boolean progress) {
    }

    @Override
    public void onVideoChatStateChange(CallState callState, VideoChatConfig chat) {
        //... STUFF 
    }
};
